How to fix the issue 'ArrayIndexOutOfBoundsException'?

Question

This is the error occurs in logcat,can anyone tell what's the meaning?

private int getDayIdxInTrip(int position) {
DayTagItem item = null;
    Integer dayIdx = -1;
    try {
        if (mTripItems.get(position).mViewType == TripDetailAdapter.DAYTAG_TYPE) {
            item = (DayTagItem) mTripItems.get(position);
        } else {
            Logger.e(TAG, "Wrong view type found on position == "
                    + position);
            position--;
            return getDayIdxInTrip(position);
        }
        dayIdx = Integer
                .parseInt(item.mDayIdx != null
                        && !item.mDayIdx.trim().equals("")
                        && !item.mDayIdx.trim().equalsIgnoreCase("null") ? item.mDayIdx
                        : "0");
    } catch (Exception e) {
        Logger.e(TAG, "getDayIdxInTrip() error!"+e.getMessage());
    }
    Logger.i(TAG,"returned"+dayIdx);
    return dayIdx;
}

From documentation:

Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array.

Example:

int myArray = new int[10];
myArray[11] = 123;

Without the code we cannot help much.
